[0002] At present, the feeding mode of the filter press generally sends raw materials into the filter chamber of the filter press, and the industry mainly adopts the combination mode of horizontal centrifugal pumps and plunger pumps for feeding. Since the plunger pump has high pressure and low motor power demand, the use proportion is gradually increasing. However, the feeding of the plunger pump is through reciprocating work of the piston to press out the liquid, so the reciprocation of this stroke will cause the actual feeding pressure to be in an up-down fluctuation state. The filter chamber of the filter press is a closed structure, and under this fluctuating pressure, the equipment, support and pipeline will vibrate greatly. Because of the arching phenomenon caused by the mutual accumulation of PVC materials, the falling of the materials is affected, resulting in poor transportation. Artificial dredging is often needed at the bottom of the feeder to ensure normal production, thereby causing low production efficiency. SUMMARY

In other cases, detailed descriptions of well-known systems, devices, circuits and methods are omitted to avoid unnecessary details that hinder the description of the present application.

[0028] Please refer to Figs. 1 to 3 The application provides an inlet pressure stabilizing device, which comprises a buffer assembly 20, a plurality of plunger pumps 10 and a plurality of filter presses 30.

[0029] Specifically, the buffer assembly 20 is internally defined to form a containing cavity for containing materials, and the buffer assembly 20 is respectively provided with a discharge port and a feeding port in communication with the containing cavity, and the discharge port and the feeding port are respectively connected with a feeding pipe and a discharge pipe; the discharge ends of the plurality of plunger pumps 10 are connected in series with each other and connected with one end of the feeding pipe away from the buffer assembly 20; the inlets of the plurality of filter presses 30 are connected with one end of the discharge pipe away from the buffer assembly 20.

[0030] It should be noted that the above-mentioned "plurality" means one or more than one, which can be determined according to the actual situation, and is not limited.

[0031] Exemplarily, the buffer assembly 20 can be made of metal material, so that the buffer assembly 20 has sufficient strength to avoid extrusion deformation during use. However, it should be noted that the metal material needs to have corrosion resistance to prevent damage to the buffer assembly 20 due to the corrosive raw material.

[0032] Based on the above technical features, the feed pressure stabilizing device uses multiple plunger pumps 10 to pass the raw material into the buffer assembly 20, and then uses multiple filter presses 30 to input the raw material in the buffer assembly 20 into the processing equipment for processing. The buffer assembly 20 cleverly absorbs the pressure fluctuations of the plunger pump 10 during operation, ensuring that the pressure of the filter press 30 is balanced, without the need for manual unblocking, ensuring normal production and improving production efficiency.

[0033] In one possible implementation, the plunger pump 10 is provided with three, namely the first plunger pump, the second plunger pump and the third plunger pump, and the discharge ends of the first plunger pump, the second plunger pump and the third plunger pump are connected to the feed pipe through the first connecting pipe; the filter press 30 includes the first filter press, the second filter press and the third filter press, and the first filter press, the second filter press and the third filter press are connected to the discharge pipe through the second connecting pipe. In this way, the first plunger pump, the second plunger pump and the third plunger pump are connected in series through the first connecting pipe and the feed pipe, and then the raw material is first passed into the buffer assembly, so that the pressure fluctuations generated by the first plunger pump, the second plunger pump and the third plunger pump during operation can be absorbed in the buffer assembly 20, and finally the raw material in the buffer assembly 20 is transported to the corresponding processing equipment for processing through the first filter press, the second filter press and the third filter press, ensuring that the pressure of the filter press is balanced, without the need for manual unblocking, ensuring normal production and improving production efficiency.

[0034] In addition, it should be noted that the present embodiment uses three plunger pumps 10 and correspondingly uses three filter presses 30 to jointly feed the raw material, which can effectively improve the production efficiency.

[0035] In one possible implementation, the buffer assembly 20 includes a tank body 21, a pressure relief pipe 22, a pressure relief valve 23 and a plurality of support legs 24. The inside of the tank body 21 defines a receiving cavity, the plurality of support legs 24 are connected to the outside of the tank body 21 in a ring shape, one end of the pressure relief pipe 22 is connected to the top of the tank body 21, and the pressure relief valve 23 is arranged on the pressure relief pipe 22 and used to control the opening and closing of the pressure relief pipe 22. In this way, the opening of the pressure relief valve 23 is controlled by observing the pressure change value in the tank body 21, so that the pressure in the tank body 21 is relieved through the pressure relief pipe 22, thereby ensuring that the pressure generated by the plunger pump 10 can be eliminated.

[0036] Exemplarily, the connection between the support leg 24 and the tank body 21 can be by welding to ensure that the support leg 24 is more firmly connected to the tank body 21, thereby avoiding the support leg 24 from being separated from the tank body 21 and failing to support the tank body 21.

[0037] Exemplarily, the reinforcing plate 240 is arranged at the bending portion of the pressure relief pipe 22, and the two ends of the reinforcing plate 240 are connected to the vertical section and the horizontal section of the pressure relief pipe 22, respectively, so as to strengthen the pressure resistance of the bending portion and avoid affecting the normal pressure relief due to the bending.

[0038] In a possible implementation, the end of the support leg 24 away from the tank body 21 is bent in the horizontal direction to form a mounting block 25, and the mounting block 25 is provided with a mounting hole 25a. In this way, the support leg 24 is placed on the placement surface, and at this time, the mounting block 25 is in contact with the placement surface. Then, the mounting hole 25a is used to pass through the placement surface to be fixedly connected, so that the tank body 21 can be fixed, and movement of the tank body 21 during use is avoided, thereby affecting the use effect.

[0039] In a possible implementation, the two sides of the tank body 21 are respectively provided with the first extension pipe 26 and the second extension pipe 27 extending outward, the first extension pipe 26 and the second extension pipe 27 are both in communication with the accommodating cavity, and the ends of the first extension pipe 26 and the second extension pipe 27 are respectively provided with the first butt joint block 28 and the second butt joint block 29. The end of the discharge pipe and the end of the feeding pipe extending toward the tank body 21 are respectively provided with the third butt joint block and the fourth butt joint block, the third butt joint block is in butt joint with the first butt joint block 28, and the fourth butt joint block is in butt joint with the second butt joint block 29.

[0040] In a possible implementation, the first butt joint block 28 and the second butt joint block 29 are both provided with a first fixing hole, and the third butt joint block and the fourth butt joint block are both provided with a second fixing hole matched with the mounting hole 25a.

[0041] Exemplarily, since the discharge pipe and the feeding pipe adopt the same connection mode with the first extension pipe 26 and the second extension pipe 27, respectively, the following embodiment takes the connection mode of the discharge pipe and the first extension pipe 26 as an example for description, and the connection mode of the feeding pipe and the second extension pipe 27 can be referred to the connection mode of the discharge pipe and the first extension pipe 26, which will not be described herein. The connection mode of the discharge pipe and the first extension pipe 26 is as follows.

[0042] The end of the discharge pipe is in butt joint with the first extension pipe 26, and at this time, the first mounting block 25 and the third mounting block 25 are aligned, so that the first fixing hole and the second fixing hole are aligned. Then, a fastener (such as a bolt) is used to pass through the second fixing hole and the first fixing hole in sequence, so as to realize the communication between the discharge pipe and the inside of the tank body 21, and the structure is simple and convenient to disassemble.

[0043] In a possible implementation, a fixing plate 210 is further arranged on the outer surface of the buffer assembly 20, the upper end and the lower end of the fixing plate 210 respectively extend outwardly with a first fixing block 220 and a second fixing block 230, the first fixing block 220 and the second fixing block 230 are both provided with a through hole, and the pressure relief pipe 22 is fixed to the fixing plate 210 by penetrating the through hole. In this way, the pressure relief pipe 22 is fixed and connected to the outer side of the tank body 21 by connecting the fixing plate 210 to the outer surface of the buffer, extending the first fixing block 220 and the second fixing block 230 outwardly at the upper end and the lower end of the fixing plate 210, and then penetrating the through hole of the first fixing block 220 and the second fixing block 230 with the pressure relief pipe 22, which is simple in structure, convenient to disassemble and assemble, and convenient for subsequent replacement or maintenance of the pressure relief pipe 22.

[0044] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application; it should be pointed out that for ordinary skilled in the art, the above technical features can be freely combined without departing from the concept of the present application, and a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application should belong to the scope of the claims of the present application.
